NullPointerException in response.header(String, int)

[mpkusnierz]

spark.http.matching.ResponseWrapper needs to override this method spark.Response.header(String, int) and call the delegate to add the int Header; otherwise this method throws a NullPointerException

java.lang.NullPointerException: null
at spark.Response.header(Response.java:166)

Yes, I believe you are right. I fixed the code in the unofficial release-5, which I'm planning to release within the next week (if all goes smoothly).
